This invention relates to lmprovements in dump cars. One of the objects of the invention is to provide improvements whereby the. capacity of dump cars of the types now in service may be increased without changing the overall dimensions thereof.

Anotherooject of the invention is to so' arrange the hopper doors of dump cars that the cars may be unloaded in qu1cker time than is now the case without necessarily changing the door opening area of the hop ers. Another and more specific'object of the invention is to provide a novel form of hoper door for dump cars which maybe used in place of the ordinary hopper doors now used, which improved hopper door will materially increase the capacity of the car and without increasing the cost.

The invention furthermore consists in the improvements in the parts and devices and in the novelcombinations of the parts and devices herein shown, described and claimed. In the drawing formin a part of this specification, Figure 1 is a longitudinal, ver tical sectional view of one type of hopper dump car showing my improvement in connection therewith, slightly more than half 4 of the car being illustrated. F 1g. 2 1s a transverse. sectional view of the car illustrated in Fig. 1 and taken substantiallypri the line 22 of'thelatter. AndFigsT3 and 4 are views 'correspondingrespectlvely with Figs. 1 and2 andillustrating my 1mprove-. ment's' in connection with another type of car, Fig. 1 being taken-on the line 4-4 of Fig. 3. I 'Referri'ng first to Figs. 1 and"'2', the 1mproved dump car, as shown, is provided with side walls 10, short, vertical end walls 11, built-up center sill 12, end bottom hopper sheets 13' and outwardly and downwardly inclined hopper bottom sheets I l. Vertical 5 transverse hopper sheets 15 and 16 are also mnployed, the hoppers belng arranged longi- Specification of'Letters Patent. Patent d Aug. '7, i917.

and on opposite sides of the center s1ll,th'ere preferably beingfour hoppers n all, two on' each side.

Referring now more particularly to Fig. 2, 1t Will be seen that the hopper designated. generally ing hopper and the door openingth-ereof is adapted to be closed by my improved door The improved door B, as shown, comprises a main-plate 17 having angled, longitudinally extending flange 18 tudinally of the car along itsup'p'er edge, and tria1 1gular'shaped end walls-or flanges 19-19. Each door B is preferably provided with a pair of hinge butts 20--20 secured to the outer faces thereof along the upper flange l8 and'back of the main plate 17, said hinge butts 20 being pivoted to depending brackets. 21-21 secured to longitudinally extendingangles 22, the latter in turn being riveted to the downwardly extending side walls 10 and side stakes 23 of the car. In order to operate each pair of doors B on each side of the, center sill,\ simultaneously, I have provided a-Z bar 24 whichextendslongitudinallyof the doors 1 and is secured 'to' the outer sides thereof.

The door operating mechanism is connected with the 2 bars, each door operating mecha- I11S1I 1 comprisinga relatively long, pivoted,

by the reference A is a side dump '65 a right hook shaped 1ink25, the latter in turn being pivoted to a short link 26, said link 26 being pivoted to another link 27, the latter .in turn being pivoted to an'integral arm 28 formed on the hub or drum 29, mounted on a longitudinally extending shaft 30 which is mounted in suitable depending brackets 31- secured to' the underside of the built-up center sill." As willbe understood, the door operatingmechanism; is the same for" each set of doors and is so arranged thatwhen the doors are incl o sed position, the mechanism -isself lh c ked' andTthe slmftij] relieved of torsion, in a well known manna I have not shown the means for operating the shaft 30, since I do not deem it/necessar'vg'it beingnnderstoodthattlie same-will be operfilled from a transverse shaft with suitable connections thereb'etween andthe shaft 30.

Referring now to the structure illustrated in Figs. 3 and 4. the dump car illustrated thereinis of the so-called W shape type wherein are provided four hoppers A A, two on each side of the center sill 112. the hoppers A being arranged in pairs. two at each end and adapted to dump toward the center of the car. Each hopper A is procar, the latter meeting operated v simiiiltaneuosly,

thereto at its center a turn being pivoted to a vided with an inclined bottom 113 which extends from the end wall 111, longitudinally extending inner and outer hopper sheets 11% and 115, and transversely extending in clined hopper sheets 116 at the center of the at the longitudinal center of the car and forming an apex or ridge to thereby divert the coal or other inaitcrial to the hoppers and prevent bridging to? ot the material,

. ln this type of cars, I employ similar hopper doors B, the latter being hinged along their upper edges by butt-s 120 pivoted to brackets 121 secured to atransversely extending angle iron 122, the latter in turn being secured to the under side or the hopper sheet 116., Each set of hopper doors B, at each end of the car, is

and for this purpose I provide a transversely extending built-up bar 124,-the latter having secured beneath the center sill and between the two doors B, an eye bolt ldrto which is pivoted a link n, the latter in lever arm 12 formed integral with a drum 18 mounted on the car. .l urthermore,

1 gra'vityfof p latter is lowered. This minimlzes danger of thewheels climbing the rails cross shart 4A, the latter being mounted in suitable brackets, as will be understood, and operated from the side of the car.

From the preceding description, it will be seen that the improved hopper doors B and B are substantially of scoop form and that the load capacity of thecar is increased by an amount substantiallyequaling the volume defined by the outlines of the doors B and i3. Inasmuch as there are tour ot these doors to the car, in the types which 1 have illustrated, it is apparent that the increased capacityis considerable, and that this increased capacity is obtained without in any way afiecting the overall dimensions of the this increased capacity is obtained insuch a manner that the center of both. the car and the load of the and permits high speed of the car with safety. It will also be apparent that upon opening the doors l3 and B, "he 'load'is released much quicker than with the ordinary type of fiat .door since the scoop shape of the doors causes, the latter to swing out from under the load'near the top of the door openings which is not true of the ordinary hinged flat doors; Furthermore, t will be noted that any improved type titted for the common of doors may be substiform of doors; they may be cheaply manufactured; the doors are strong and rigid inasmuch as the triangular shaped. end walls 19 serveas strengthening and the corrugations 50. which eX- means of the hingencense tend transversely of. the doors, also brace them.

Although l have herein shown and do" scribed what- I now consider the improved method of carrying out my invention, the same is merely illustrative and it is obvious that changes in the details of construction may be made without departing from the spirit of the invention, and also that the improved doors are adaptable for dump cars of other types than those illustrated herein.

1 claim:

1. A hopper car of the character described having a center sill and side walls with longitudinally extending hoppers, each of said hoppers having triangular shaped end hopper sheets and a downwardly and outwardly inclined hopper bottom sheet, and hinged doors for said hoppers, each of said doors comprising a main portion with a longitiu dinally extending flange substantially at right angles to the main portion and sub stantially. right angled. triangular shaped ends, whereby said doors are scoop shaped and adapted to carry a part of the car load and lower the center of gravity of the car,

said flange being disposed uppermost and.

the door being hinged from said flange adthe main portion of each door normally being inclined downwardly and inwardly, the door when swung open having the main portion thereof inclined downwardly and outwardly whereby the door automatically clears itself of the load and the load of the car is discharged outwardly.

2. In, a hopper car of the character described having a plurality of hoppers intermediate the trucks, each of said hoppers including a downwardly inclined hopper bottom sheet, and doors for closing each of said hoppers, each of said doors comprising a main portion with a flange at right angles thereto extending longitudinally along the top of the door, said doors being hinged from said flanges, each of said doors having also triangular shaped ends to thereby'adapt each doonfor carrying a part of the load,

said doors being arranged to swing about axes parallel to the plane of the main portions thereof, the main portions of said doors being corrugatct l substantially as specified,
